Cleaning plants for washing waters of galvanic production

摘要

1. Installation for the purification of washing water in electroplating, comprising two ion exchangers loaded ion exchange filter - cation and anion exchange, containers for reagent solutions, transport and bypass lines for supplying and removing fluids, valves and measuring means and control parameters, characterized in that setting introduced second cation exchanger, connected in series with the first and equipped similarly he transport lines and valves, and means for supplying compressed air and plaster in, wherein the container cation filters reagent solutions is made two-piece, yield anion filter through transport lines and valves connected to both sections of the two-part filter, the input and output of each filter are connected through transport lines and valves to a compressed air supply means, and the inner diameter ratio d of each of the filters to the height h of the ion exchanger is determined by the expression 0.5 d / h 0,25.2. Apparatus according to claim 1, characterized in that the cation exchanger is used as ion exchanger iminodiacetate.
